Withthe change of fertility concepts, more and more women over the age of 40 are beginning to consider preparing for pregnancy. However,"40+ still want to fight for a second child, can they still expel healthy eggs? How many can you use at a time? "Such questions express the aspirations of countless elderly women planning to conceive. Scientific data shows that women over the age of 40 do face fertility challenges, but through scientific evaluation and intervention, they still have the opportunity to obtain healthy eggs and realize their mother's dream.
The "stock" of female follicles is fixed from birth and will only decrease and will not regenerate.
"",.There are about 1 - 2 million follicles at birth, which have dropped to 300,000 - 500,000 during puberty. The decline accelerates after the age of 35, and only less than 10% are left after the age of 40.
40,,5-10,.Women with better ovarian function may get close to 10 eggs, while those with poor ovarian function may only get 3-5 eggs or less.
Aging has a more significant impact on egg quality.
.As women age, the risk of chromosomal abnormalities in eggs increases significantly. The egg aneuploidy rate (chromosomal abnormalities) in women over the age of 40 may exceed 50%, which directly leads to reduced fertilization rates, abnormal embryo development or increased risk of abortion.
.Mitochondria are the egg's "energy factory", providing energy for embryo division. Aging leads to the decline of mitochondrial function and insufficient energy supply, which will affect the development and implantation of embryos.
AMH (anti-Muller hormone) testing is an important indicator for assessing ovarian reserve.
AMH().AMH levels below 1.1 ng/mL usually indicate a decrease in ovarian reserve, which is common in women over the age of 40.
(FSH)2-3,.FSH levels above 10mIU/mL indicate that ovarian responsiveness may be poor.
(AFC),10mm.AFC is an important indicator of ovarian responsiveness.
Nutritional supplementation strategies have a positive impact on improving egg quality.
Nutritional supplementation strategies can have a positive impact on improving the quality of eggs.Coenzyme Q10 (100-300mg/day)can improve mitochondrial function and increase egg energy supply.DHEA (50mg/day) issuitable for people with low AMH.Vitamin D(2000IU/day) needs to be supplemented continuously for 3 months. It is closely related to follicular development and hormone balance.
.30 minutes of moderate-intensity exercise every day can improve ovarian blood flow; ensuring 7-8 hours of high-quality sleep helps balance hormones; reducing stress and reducing cortisol levels through meditation, yoga and other methods to create an internal environment conducive to egg development.
Personalized ovulation promotion programs are the key to meeting the challenge of fertility at advanced age.
.For women over the age of 40, doctors may recommend a microstimulation regimen or a mild stimulation regimen, which, while harvesting fewer eggs, tend to be of higher quality and reduce the risk of ovarian hyperstimulation syndrome.
(PGT-A).For women over the age of 40, the risk of miscarriage is significantly reduced.
.Time-lapse imaging system can screen embryos with synchronous division; blastocyst culture (transfer on day 5) can screen embryos with high development potential.
The natural pregnancy rate after 45 years of age is extremely low.
45.But it is not completely hopeless.
40,.The key is to first objectively understand your own situation, clarify the ovarian status through comprehensive examination, and then formulate a personalized plan under the guidance of a professional doctor. The creation of life is never a simple game of quantity, but a perfect combination of quality and timing. For women who are determined to prepare for pregnancy at the age of 40, scientific understanding, reasonable expectations and perseverance are the keys to welcoming new life.
